Theoretical Studies of the Method of Electromagnetic Mechanical Activation

The paper focuses on the current state of the problem associated with increasing the energy efficiency of mechanical activation processes in the hardware-technological systems of the AIC. It was revealed that the priority direction is the electrophysical intensification of processes in devices with a magnetic fluidized layer. It was established that traditional mechanical activation methods in devices with a vortex electromagnetic field are energy-intensive and do not provide product particles with a given technology of dispersion and high selectivity. An unconventional method of mechanical activation using the energy of a constant electromagnetic field is proposed. The mechanism of its formation was revealed by the method of high-speed fixation (ultra-rapid). The regularities of the emergence and destruction of clusters of a magnetically fluidized layer with the creation of adjustable energy-stressed shock-abrasive loads in contact systems of ferromagnetic elements were established. The basic theoretical principles of the method are formulated based on the development of the hypothesis of J. K. Maxwell about the dipole interaction of spherical metal bodies in a magnetic field. As a result of theoretical and experimental research, mathematical models were obtained that describe the physical and mechanical processes of the formation of power contacts in the working volumes of electromagnetic mechanical activators. The description of the magnetic field was carried out using the ANSYS software package. The results of experimental studies confirm the adequacy of physical and mathematical models to real processes. The basic theoretical provisions and mathematical models formulated in the paper are of great practical importance and allow designing devices that meet the requirements of production, both in terms of selectivity and processing quality, and in terms of energy intensity.
